Book Description
The observational theoretical and empirical problems of determining the contribution of earthlight to the night-time illumination on the moon have been considered in detail. A photographic survey program to determine the absolute intensity of the earthlight portion of the moon is described. An empirical phase curve relating the mean magnitude difference between the earth and the sun has been derived from visual photometry measurements. The problems of predicting the albedo of the earth as well as predicting the mean albedo of specific location on the lunar surface are reviewed. Theoretical and empirical determinations of the photometric function of the lunar surface are discussed. Tables and graphs of relative surface brightness under earthlight are presented for a number of locations on the moon. These include information about nine APOLLO sites as well as locations every 5 deg. of longitude and latitude between plus or minus 50 deg. longitude and latitude. The tables are for zero libration. Although the tables and graphs have been compiled under simplifying assumptions; instructions for making the necessary corrections to specific situations are discussed.

Book Description
This fascinating book will stay with children every time they gaze up at the night sky. Through vivid pictures and engaging explanations, children will learn about many of the Moon’s mysteries: what makes it look like a silvery crescent one time and a chalk-white ball a few nights later, why it sometimes appears in the daytime, where it gets its light, and how scientists can predict its shape on your birthday a thousand years from now. Next Time You See the Moon is an ideal way to explain the science behind the shape of the Moon and bring about an evening outing no child—or grown-up—will soon forget. Awaken a sense of wonder in a child with the Next Time You See series from NSTA Kids. The books will inspire elementary-age children to experience the enchantment of everyday phenomena such as sunsets, seashells, fireflies, pill bugs, and more. Free supplementary activities are available on the NSTA website. Especially designed to be experienced with an adult—be it a parent, teacher, or friend—Next Time You See books serve as a reminder that you don’t have to look far to find something remarkable in nature.

Book Description
The age-old question of how our home planet and its satellite originated has in recent times undergone a minor revolution. The emergence of the "giant impact theory" as the most successful model for the origin of the Moon has been difficult to reconcile with some aspects of the Earth, and the development of an integrated model for the origin of the Earth-Moon system has been difficult for this reason. However, recent technical advances in experimental and isotopic work, together with intensified interest in the modeling of planetary dynamics, have produced a wealth of new results requiring a rethinking of models for the origin of the Earth and Moon. This book is intended to serve as a resource for those scientists working closely in this field, while at the same time it provides enough balance and depth to offer an introduction for students or technically minded general readers. Its thirty chapters address isotopic and chemical constraints on accretion, the dynamics of terrestrial planet formation, the impact-triggered formation of the Earth-Moon system, differentiation of the Earth and Moon, the origin of terrestrial volatiles, and conditions on the young Earth and Moon. Covering such subjects as the history and origin of the Moon's orbit, water on the Earth, and the implications of Earth-Moon interactions for terrestrial climate and life, the book constitutes a state-of-the-art overview of the most recent investigations in the field. Although many advances have been made in our ability to evaluate competing models of the formation of the Earth-Moon system, there are still many gaps in our understanding. This book makes great strides toward closing those gaps by highlighting the extensive progress that has been made and pointing toward future research.

Book Description
This extraordinary book details how the Moon could be used as a springboard for Solar System exploration. It presents a realistic plan for placing and servicing telescopes on the Moon, and highlights the use of the Moon as a base for an early warning system from which to combat threats of near-Earth objects. A realistic vision of human development and settlement of the Moon over the next one hundred years is presented, and the author explains how global living standards for the Earth can be enhanced through the use of lunar-based generated solar power. From that beginning, the people of the Earth would evolve into a spacefaring civilisation.

Book Description
Lunar Science: A Post-Apollo View: Scientific Results and Insights from the Lunar Samples explains the scientific results and discoveries of the manned Apollo lunar missions as they are understood. The emphasis is less on sample description and data and more on the interpretative aspects of the study, with the aim of providing a coherent story of the evolution of the moon and its origin as revealed by the lunar samples and the Apollo missions. This text has seven chapters; the first of which provides a historical background of efforts to study the moon prior to the Apollo missions, including lunar photogeologic mapping and direct exploration by spacecraft. Attention then turns to the Apollo missions and the lunar samples collected, beginning with Apollo 11 that landed on the moon on July 20, 1969 and followed by more missions. The next chapter describes the geology of the moon, with emphasis on craters, central peaks and peak rings, the large ringed basins, rilles, and maria lava flows. The reader is also introduced to the nature of the lunar surface material, the maria basalts, the highlands, and the moon’s interior. This book concludes with a discussion on the evidence that has been gathered by the Apollo missions that offers insights into the origin and evolution of the moon. An epilogue reflects on the usefulness of manned space flight. This book will appeal to lunar scientists as well as to those with an interest in astronomy and space exploration.

Book Description
An intimate portrait of the Earth's closest neighbor--the Moon--that explores the history and future of humankind's relationship with it Every generation has looked towards the heavens and wondered at the beauty of the Moon. Fifty years ago, a few Americans became the first to do the reverse--and shared with Earth-bound audiences the view of their own planet hanging in the sky instead. Recently, the connection has been discovered to be even closer: a fragment of the Earth's surface was found embedded in a rock brought back from the Moon. And astronauts are preparing to return to the surface of the Moon after a half-century hiatus--this time to the dark side. Oliver Morton explores how the ways we have looked at the Moon have shaped our perceptions of the Earth: from the controversies of early astronomers such as van Eyck and Galileo, to the Cold War space race, to the potential use of the Moon as a stepping stone for further space exploration. Advanced technologies, new ambitions, and old dreams mean that men, women, and robots now seem certain to return to the Moon. For some, it is a future on which humankind has turned its back for too long. For others, an adventure yet to begin.

Book Description
Global change involves complex and far-reaching variations in the Earth’s systems, and satellite observations have been widely used in global change studies. Over the past five decades, Earth observation has developed into a comprehensive system that can conduct dynamic monitoring of the land, the oceans and the atmosphere at the local, regional and even global scale. At the same time, although a large number of Earth observation satellites have been launched, very few of them are used in global change studies. The lack of scientific satellite programs greatly hinders research on global change. This book proposes using a series of global change scientific satellites to establish a scientific observation grid for global environmental change monitoring from space, and offers the first comprehensive review of lunar-based Earth observation. These scientific satellites could provide not only basic datasets but also scientific support in facilitating advances in international global change research.
